From Black Hawk Down:

Hoot: Once that first bullet goes past your head, politics and all that shit just goes right out the window.

Grimes: Why aren’t you shooting?
Waddell: We’re not being shot at yet.
Grimes: How can you tell?
Waddell: A hiss means it’s close. A snap means…
[a bullet whizzes close by]
Waddell: Now they’re shooting at us!

McKnight: “Don’t let that man crawl! Somebody help that man!”
